Is getting this a good idea for a student?

I'm a 20 year old pre final year engg. Student with a Credit score of 750 due to my education loan and a gold loan. Swiggy is offering me this HDFC LTF card, ik building a credit history is very important nowadays and using credit cards is one of a good idea (if it is used correctly).

Currently I don't have a big income, earing 5k as a stipend from a startup and some mere amount of pocket money from my parents. My questions are 1. Is it even a good idea? Or Should I wait for 1 or more years to get a CC after getting a proper job? 2. am I really eligible for this card? Will I get rejected if I apply? 3. Incase if I apply what are the documents and procedures I need to submit or to do?

since I'm a lower middle class student, Getting a CC will help me with buying my essential stuffs with EMI and other cashback benefits too.

Thanks in advance!

PS. I'm financially well disciplined so I'm not worried about over spending above my ability to repay. I always repay my simpl bills on time and I have a limit of 11.5k in simpl
